What is a good example of ballistic flight?

Ballistic flight describes the motion of an object that is subjected to the force of gravity and aerodynamic drag after being propelled and released. A bullet is a prime example of ballistic flight because it follows a parabolic trajectory after it is fired from a gun. Once the bullet is in motion, it continues on its path primarily due to its initial velocity, with gravity pulling it downward and air resistance acting against its motion.

Other options represent different types of flight. A glider relies on lift to remain airborne and can stay aloft for extended periods by using rising air currents. A drone is actively controlled and can maneuver in various ways, relying on thrust from its motors. The space shuttle, while it undergoes phases of ballistic flight after re-entering the atmosphere, primarily operates through powered flight during the ascent, making it a less straightforward example compared to the direct trajectory of a bullet. Thus, the bullet is the clearest representation of ballistic flight due to its simple motion influenced mainly by gravitational and drag forces after being initially propelled.
